Answer:
take the number (x,y) take Y subtract 2.. take x add 5. if the origin is 0,0 it would end 5,-2. if Q is 7,3
7+5 = 12
-3-2 = -5
answer (12,-5)
Step-by-step explanation:
Answer:
try this answer x2 + 2xy + y2 - 16
Answer:
$5.63
Step-by-step explanation:
Just add both prices together
Product of zeroes of a cubic polynomial is -d/a of cubic polynomial ax^3 + bx^2 + cx + d
<span>So we know product of two zeroes therefore by putting value of product of two zeroes and taking third as a variable we get third zero as -2 </span>
<span>Therefore -2 satisfies the equation and x+2 will be a factor of the equuation </span>
<span>By diving the above equation by x+2 we will get a quadratic rquation </span>
<span>I.e. x^2 -7x + 12 </span>
<span>Now by splitting the middle term you can find the other two zeroes </span>
<span>i.e. x^2 - 4x -3x + 12 </span>
<span>X(x - 4) -3(x - 4) </span>
<span>Therefore (x-3)(x-4)= x^2 - 4x -3x + 12 </span>
<span>Therefore the other two zeroes are 3 and 4 </span>
<span>The zetoes for the cubic equation are -2, 3 , 4 </span>
<span>To verify you can put these values in the equation and find answer = 0</span>
Answer:
The correct option is A) This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the probability of obtaining a value equal to or more extreme than the sample proportion is . which is not unusual.
Step-by-step explanation:
Consider the provided information.
The formula for testing a proportion is based on the z statistic.
Were 
is sample proportion.
hypothesized proportion and n is the sample space,
The proportion of Americans who were afraid to fly in 2006 was 0.10. A random sample of 1,300 Americans results in 143 indicating that they are afraid to fly.
Therefore, n = 100 
, 
and 
Substitute the respective values as shown:
P(x>sample proportion)=p(z>1.20)=0.11507
Hence, the correct option is A) This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the probability of obtaining a value equal to or more extreme than the sample proportion is . which is not unusual.
